DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1. Form for Advising Cleaning of Vehicle Cabin Interior

With reference to FIG. 1 , a description will be made about a form in which a vehicle management system 1 recognizes a dirt factor element in a vehicle cabin of a vehicle 10 and a use situation of the vehicle 10 and advises cleaning of a vehicle cabin interior of the vehicle 10. The vehicle management system 1 includes a vehicle control device 20 installed in the vehicle 10 and a vehicle renting system 100 performing communication with the vehicle control device 20 via a communication network 500.

The vehicle 10 is a rented vehicle rented to a user U by car-sharing, a car rental service, or the like and includes the vehicle control device 20 controlling an action of the vehicle 10 and an automotive navigation system (automotive navigation device) 50. The vehicle renting system 100 manages renting of the vehicle 10 while setting a parking lot St as a delivery place.

The vehicle renting system 100 includes a rented vehicle database (DB) 110 storing management data of plural rented vehicles including the vehicle 10. The rented vehicle DB 110 records information of a rented vehicle, a reservation status of a rented vehicle, information of a user of a rented vehicle, and so forth with respect to each rented vehicle.

The information of the rented vehicle includes a communication address of the rented vehicle, and the information of the user includes a communication address of a user terminal used by the user. The vehicle renting system 100 uses those communication addresses and thereby performs communication between the vehicle 10 and a user terminal 90 used by the user U via the communication network 500. Further, the vehicle control device 20 performs communication between a maintenance management server 200 managing maintenance of the vehicle 10 and a weather information server 300 providing weather information via the communication network 500. The user terminal 90 is a communication terminal such as a smartphone, a portable terminal, or a tablet terminal, each of which is carried and used by the user U.

The user U who reserves renting of the vehicle 10 starts use of the vehicle 10 from the parking lot St, returns the vehicle 10 to the parking lot St, and then finishes use of the vehicle 10. During use by the user U, the vehicle control device 20 of the vehicle 10 acquires information in the vehicle cabin (images, sounds, smells, and so forth in the vehicle cabin) of the vehicle 10 and recognizes an element that may become a factor of occurrence of dirt such as eating and drinking in the vehicle cabin (dirt factor element).

Further, the vehicle control device 20 recognizes an area or facility visited by the user U by the vehicle 10 and traveling of the vehicle 10 in predetermined weather (for example, bad weather such as rain or snow) based on positions of the vehicle 10 recognized by the automotive navigation system 50. In FIG. 1 , as illustrated by A1, the user U visits a campsite (corresponding to a predetermined facility of the present invention) on a rough ground with a child K by the vehicle 10, and the child K is eating and drinking in the vehicle cabin. Further, as illustrated in A2, the vehicle 10 travels in rainy weather.

When the vehicle control device 20 recognizes the dirt factor element and recognizes that the vehicle 10 is used in a situation, in which dirt is likely to occur, such as A1 or A2, the vehicle control device 20 transmits first vehicle cleaning information CLi1 to the user terminal 90 in order to advise cleaning of the vehicle cabin interior when the vehicle 10 is returned. Further, when the user U does not clean the vehicle cabin interior of the vehicle 10 in response to transmission of the first vehicle cleaning information CLi1, the vehicle control device 20 transmits second vehicle cleaning information CLi2 to the maintenance management server 200 and requests cleaning of the vehicle cabin interior of the vehicle 10.

Cleaning of the vehicle cabin interior of the vehicle 10 by the user U is advised by transmission of the first vehicle cleaning information CLi1, cleaning of the vehicle cabin interior of the vehicle 10 is requested to the maintenance management server 200 by transmission of the second vehicle cleaning information CLi2, and dirt in the vehicle cabin of the vehicle 10 may thereby be prevented from being left.

2. Configuration of Vehicle Management System

A configuration of the vehicle management system 1 will be described with reference to FIG. 2 . The vehicle management system 1 is composed of the vehicle control device 20 installed in the vehicle 10 and the vehicle renting system 100.

The vehicle control device 20 is an electronic control unit (ECU) composed of a central processing unit (CPU) not illustrated, a memory 30, and so forth. The vehicle 10 includes the vehicle control device 20, a communication unit 40, a touch panel 41, a speaker 42, a vehicle cabin camera 43, a microphone 44, an odor sensor 45, a load sensor 46, a rain sensor 47, a start switch 43, the automotive navigation system 50, a battery 60, and so forth.

The communication unit 40 is an interface for performing communication among the vehicle renting system 100, the maintenance management server 200, and the weather information server 300 via the communication network 500. The communication unit 40 receives, as an input, information output from the vehicle control device 20, transmits the information to the outside, and outputs information received from the outside to the vehicle control device 20.

The touch panel 41 is configured by arranging a touch sensor on a surface of a flat display such as a liquid crystal panel, inputs an operation signal of the touch sensor to the vehicle control device 20, and changes a display screen in accordance with a control signal output from the vehicle control device 20. The speaker 42 amplifies a sound signal output from the vehicle control device 20 and outputs that to the vehicle cabin interior.

The vehicle cabin camera 43 photographs the vehicle cabin interior and outputs the image of the vehicle cabin interior to the vehicle control device 20. The microphone 44 detects a sound in the vehicle cabin and outputs a sound signal to the vehicle control device 20. The odor sensor 45 detects an odor in the vehicle cabin and outputs an odor detection signal to the vehicle control device 20. The load sensor 46 detects a load exerted on a seat (not illustrated) of the vehicle 10 and outputs a load detection signal indicating a load level to the vehicle control device 20.

The rain sensor 47 detects a water drop dropping on a windshield (not illustrated) or the like of the vehicle 10, thereby detects rainy weather, and outputs a rainy weather detection signal to the vehicle control device 20. The automotive navigation system 50 includes a Global Positioning System (GPS) sensor (not illustrated) and map data and performs a route guidance to a destination based on the present position of the vehicle 10 detected by the GPS sensor and on the map data. The route guidance is performed by display of a guidance screen on the touch panel 41 and by an output of guidance sounds from the speaker 42.

The start switch 48 is switched between a power source ON instruction state and a power source OFF instruction state in accordance with an operation by the user U. Further, the start switch 48 outputs a power source ON instruction signal to the vehicle control device 20 when becoming the power source ON instruction state and outputs a power source OFF instruction signal to the vehicle control device 20 when becoming the power source OFF instruction state. The vehicle control device 20 starts power supply from the battery 60 to electrical equipment installed in the vehicle 10 when the power source ON instruction signal is input and stops power supply from the battery 60 to the electrical equipment when a power source OFF instruction is input. The user U turns the start switch 48 to the power source ON instruction state when use of the vehicle 10 is started and turns the start switch 48 to an OFF instruction state when use of the vehicle 10 is finished.

In the memory 30, a control program 31 of the vehicle 10, reference image data 32, and monitoring target sound data 33 are saved. In the reference image data 32, reference images for a determination about whether or not dirt is present in the vehicle cabin based on an image of the vehicle cabin interior are recorded, and in the monitoring target sound data 33, data of monitoring target sounds for a determination about whether dirt is present in the vehicle cabin based on a sound in the vehicle cabin are recorded. The CPU reads and executes a control program and thereby functions as a vehicle cabin interior information acquisition unit 21, a dirt factor element recognition unit 22, a vehicle position recognition unit 23, a vehicle use situation recognition unit 24, a weather recognition unit 25, a power source state recognition unit 26, a vehicle cleaning handling unit 27, and a vehicle cabin interior cleaning estimation unit 28.

A process executed by the vehicle position recognition unit 23 corresponds to a vehicle position recognition step in a vehicle management method of the present invention, and a process executed by the vehicle use situation recognition unit 24 corresponds to a vehicle use situation recognition step in the vehicle management method of the present invention. A process executed by the vehicle cleaning handling unit 27 corresponds to a vehicle cleaning handling step in the vehicle management method of the present invention.

The vehicle cabin interior information acquisition unit 21 acquires an image of the vehicle cabin interior photographed by the vehicle cabin camera 43, a sound in the vehicle cabin input to the microphone 44, a level of an odor in the vehicle cabin, the level of the odor being detected by the odor sensor 45, and a level of a load exerted on a seat in the vehicle cabin, the level of the load being detected by the load sensor 46, as vehicle cabin interior information of the vehicle 10.

The dirt factor element recognition unit 22 recognizes the following first element to fourth element as dirt factor elements based on the vehicle cabin interior information acquired by the vehicle cabin interior information acquisition unit 21.

First element: a situation in which an occupant contacts with food and drink. The dirt factor element recognition unit 22 extracts an image portion of the occupant and food and drink from an image of the vehicle cabin interior, the image acquired by the vehicle cabin interior information acquisition unit 21, and thereby recognizes a situation in which the occupant contacts with food and drink. Contact with food and drink by the occupant is recognized, and occurrence of dirt in the vehicle cabin may thereby be predicted, the dirt being due to spilled food accompanying eating and drinking in the vehicle cabin.

Note that recognition of a sound, whose concordance rate is a third predetermined value or greater, in a situation in which the occupant contacts with food and drink may be set as the first element, the concordance rate being obtained between the sound in the vehicle cabin and the monitoring target sound recorded in the monitoring target sound data. As the monitoring target sounds, for example, a sound in a case of opening a lid of a canned drink or a bottled drink and a sound in a case of opening a bag of a snack are used. A determination is also made about a sound in the vehicle cabin, and a situation in which dirt in the vehicle cabin highly possibly occurs may thereby be recognized as the first element.

Second element: a situation in which a child is riding in the vehicle. The dirt factor element recognition unit 22 extracts an image portion of the child from an image of the vehicle cabin interior, the image acquired by the vehicle cabin interior information acquisition unit 21, and thereby recognizes a situation in which the child is riding in the vehicle. Note that voice of the child is extracted from sounds in the vehicle cabin acquired by the vehicle cabin interior information acquisition unit 21, and a situation in which the child is riding in the vehicle may thereby be recognized. A ride of the child in the vehicle is recognized, and occurrence of dirt in the vehicle cabin due to behavior of the child may thereby be predicted.

Third element: a fact that the concordance rate between an image of the vehicle cabin interior at a finish of use of the vehicle 10 and the reference image recorded in the reference image data 32 is a first predetermined value or smaller. The vehicle cabin interior information acquisition unit 21 acquires the image of the vehicle cabin interior at the finish of use of the vehicle 10 by photographing by the vehicle cabin camera 43 at a timing when the start switch 48 is operated to OFF. As the reference image, an image of the vehicle cabin interior in a state where dirt is not present or an image of the vehicle cabin interior at a time point when the user U starts using the vehicle 10 is used. By using the concordance rate between the image of the vehicle cabin interior at the finish of use of the vehicle and the reference image, occurrence of dirt in the vehicle cabin may be estimated from the change in the situation in the vehicle cabin.

Fourth element: a fact that the level of the odor in the vehicle cabin is a predetermined level or higher. An odor emitted from food and drink is detected when eating and drinking are performed in the vehicle cabin, and occurrence of dirt in the vehicle cabin due to spilled food may thereby be predicted.

Fifth element: a fact that the concordance rate between a sound in the vehicle cabin and the monitoring target sound recorded in the monitoring target sound data 33 is a second predetermined value or greater. As described above, the sound in a case of opening a lid of a canned drink or a bottled drink or the sound in a case of opening a bag of a snack is recognized, and occurrence of dirt in the vehicle cabin due to spilled food may thereby be predicted.

Here, in the above third element, the concordance rate between the image of the vehicle cabin interior at the finish of use of the vehicle 10 and the reference image is calculated by using an image recognition technology such as template matching. Further, in the above fifth element, the concordance rate between the sound in the vehicle cabin and the monitoring target sound is calculated by analyzing the intensity of a sound such as a sound pressure, a frequency band, or the like.

The vehicle position recognition unit 23 recognizes a spot where the vehicle 10 is positioned based on the present position (latitude and longitude) of the vehicle 10 detected by the automotive navigation system 50 and the map data. The weather recognition unit 25 recognizes the weather at the spot where the vehicle 10 is positioned based on a detection situation of the rain sensor 47, weather information of an area including the present position of the vehicle 10, the weather information being acquired from the weather information server 300, and so forth.

The vehicle use situation recognition unit 24 recognizes that the user U visits a predetermined area or a predetermined facility by the vehicle 10 from the position of the vehicle 10 recognized by the vehicle position recognition unit 23. The predetermined area and the predetermined facility are set on the assumption that dirt in the vehicle cabin is likely to occur. The predetermined area is an area such as seashore or grassland where shoes or clothes of the occupant are likely to get dirty when the occupant gets off the vehicle, for example, and the predetermined facility is also a facility such as a campsite or a ski site where shoes or clothes of the occupant are likely to get dirty when the occupant gets off the vehicle. Further, the vehicle use situation recognition unit 24 recognizes that the vehicle 10 is used in bad weather such as rain or snow based on the position of the vehicle 10 recognized by the vehicle position recognition unit 23 and the weather recognized by the weather recognition unit 25.

The power source state recognition unit 26 recognizes whether the battery 60 is in a power source ON state where power is supplied from the battery 60 to the electrical equipment or a power source OFF state where power supply from the battery 60 to the electrical equipment is shut off in accordance with an ON instruction signal and OFF instruction signal output from the start switch 48. The vehicle cleaning handling unit 27 transmits the first vehicle cleaning information CLi1 to the user terminal 90 and transmits the second vehicle cleaning information CLi2 to the maintenance management server 200 when the dirt factor element recognition unit 22 recognizes at least any one of the above first element to fifth element, the vehicle use situation recognition unit 24 recognizes that the user U visits the predetermined area or the predetermined facility by the vehicle 10, and when it is recognized that the vehicle 10 travels in a situation in which the weather recognition unit 25 recognizes bad weather.

The vehicle cabin interior cleaning estimation unit 28 estimates that the user U has cleaned the vehicle cabin interior based on the vehicle cabin interior information acquired by the vehicle cabin interior information acquisition unit 21. Specifically, the vehicle cabin interior cleaning estimation unit 28 estimates that the user U has cleaned the vehicle cabin interior when at least any one of the following estimation situation 1 to estimation situation 4 is recognized.

Estimation situation 1: the concordance rate between an image of the vehicle cabin interior photographed by the vehicle cabin camera 43 after transmission of the first vehicle cleaning information CLi1 to the user terminal 90 and the reference image is higher than a first predetermined value.

Estimation situation 2: the level of the odor detected by the odor sensor 45 after transmission of the first vehicle cleaning information CLi1 to the user terminal 90 is a predetermined level or lower.

Estimation situation 3: the load detected by the load sensor 46 after transmission of the first vehicle cleaning information CLi1 to the user terminal 90 fluctuates in a prescribed width or wider through a predetermined time.

Estimation situation 4: an occupant such as the user U is present in the vehicle cabin of the vehicle 10 from a time point when the power source state recognition unit 26 recognizes that the power source ON state is switched to the power source OFF state after transmission of the first vehicle cleaning information CLi1 to the user terminal 90 until a predetermined time elapses.

3. Vehicle Cabin Dirt Handling Processing

Following flowcharts illustrated in FIG. 3 to FIG. 5 , a description will be made about vehicle cabin dirt handling processing executed by the vehicle control device 20 and the vehicle renting system 100.

FIG. 3 is the flowchart of the vehicle cabin dirt handling processing executed by the vehicle renting system 100. In step S3 in FIG. 3 , a vehicle renting management unit 101 of the vehicle renting system 100 moves the processing to step S2 when an application for renting of the vehicle 10 is made by the user U. The user U executes vehicle renting application software by the user terminal 90 and performs an operation of the application for renting the vehicle 10, and renting application information is thereby transmitted from the user terminal 90 to the vehicle renting system 100. The vehicle renting system 100 receives this renting application information and accepts the application for renting of the vehicle 10 by the user U.

In step S2, the vehicle renting management unit 101 recognizes a destination to be visited by the user U by the vehicle 10 from use plan information of the vehicle 10, the use plan information being provided from the user U, and determines whether or not the destination is the above-described predetermined area or predetermined facility. Then, the vehicle renting management unit 101 moves the processing to step S10 when the destination is the predetermined area or the predetermined facility but moves the processing to step S3 when the destination is neither the predetermined area nor the predetermined facility.

In step S10, the vehicle renting management unit 101 determines whether or not use in bad weather such as a snowstorm is predicted during a use period of the vehicle 10 by the user U based on information of predicted weather, the information being provided from the weather information server 300. Then, the vehicle renting management unit 101 moves the processing to step S11 when movement in bad weather is predicted and prohibits renting of the vehicle 10. Accordingly, use of the vehicle 10 under a condition with a very strong possibility of occurrence of dirt in the vehicle cabin may be avoided which is movement to the predetermined area or the predetermined facility in bad weather, and occurrence of dirt in the vehicle cabin of the vehicle 10 may thereby be prevented.

On the other hand, when movement in bad weather is not predicted, the vehicle renting management unit 101 moves the processing from step S2 to step S3 and permits renting of the vehicle 10 to the user U. Step S4 and subsequent steps are processes in a case where the vehicle 10 is returned, and process contents will be described later.

Next, FIG. 4 to FIG. 6 are flowcharts of vehicle cabin dirt handling processing executed by the vehicle control device 20. The vehicle control device 20 starts the processing of the flowcharts of FIG. 4 to FIG. 6 when a start of use of the vehicle 10 is recognized. The vehicle control device 20 determines that use of the vehicle 10 is started when the power source state recognition unit 26 recognizes that the power source OFF state is switched to the power source ON state.

In step S50 in FIG. 4 , the vehicle cabin interior information acquisition unit 21 photographs the vehicle cabin interior of the vehicle 10 by the vehicle cabin camera 43 and acquires an image of the vehicle cabin interior. In next step S51, the dirt factor element recognition unit 22 moves the processing to step S70 when a ride of a child in the vehicle (the above second element) is recognized from the image of the vehicle cabin interior, sets a child-in-vehicle flag to “1”, and moves the processing to step S52. Note that an initial value of each flag is set as “0”. On the other hand, the dirt factor element recognition unit 22 moves the processing to step S52 when a ride of a child in the vehicle is not recognized from the image of the vehicle cabin interior.

In step S52, the dirt factor element recognition unit 22 moves the processing to step S71 when a situation in which an occupant contacts with food and drink (the above first element) is recognized from the image of the vehicle cabin interior, sets a vehicle cabin eating-and-drinking flag to “1”, and moves the processing to step S53. On the other hand, when the situation in which the occupant contacts with food and drink is not recognized from the image of the vehicle cabin interior, the dirt factor element recognition unit 22 moves the processing to step S53.

In step S53, the vehicle cabin interior information acquisition unit 21 detects the odor in the vehicle cabin by the odor sensor 45 and acquires an odor level in the vehicle cabin. In next step S54, the dirt factor element recognition unit 22 moves the processing to step S72 when the odor level in the vehicle cabin is the predetermined level or higher (the above fourth element), sets the vehicle cabin eating-and-drinking flag to “1”, and moves the processing to step S55. On the other hand, the dirt factor element recognition unit 22 moves the processing from step S54 to step S55 when the odor level in the vehicle cabin is lower than the predetermined level.

In step S55, the vehicle cabin interior information acquisition unit 21 detects the sound in the vehicle cabin by the microphone 44. In next step S56, the dirt factor element recognition unit 22 moves the processing to step S73 when the concordance rate between the sound in the vehicle cabin and the monitoring target sound is the second predetermined value or greater (the above fifth element), sets the vehicle cabin eating-and-drinking flag to “1”, and moves the processing to step S57 in FIG. 5 . On the other hand, when the concordance rate between the sound in the vehicle cabin and the monitoring target sound is lower than the second predetermined value, the dirt factor element recognition unit 22 moves the processing from step S56 to step S57 in FIG. 5 .

In step S57, the vehicle use situation recognition unit 24 recognizes the use situation of the vehicle 10 based on the present position of the vehicle 10 recognized by the vehicle position recognition unit 23. In next step S58, the vehicle use situation recognition unit 24 moves the processing to step S74 when it is recognized that the user U visits the predetermined area or the predetermined facility by the vehicle 10, sets a target destination flag to “1”, and moves the processing to step S59. On the other hand, when the user U visits neither the predetermined area nor the predetermined facility, the vehicle use situation recognition unit 24 moves the processing from step S58 to step S59.

In step S59, the weather recognition unit 25 recognizes the weather of the spot where the vehicle 10 is positioned. In next step S60, when it is recognized that the vehicle 10 travels in bad weather based on the position of the vehicle 10 recognized by the vehicle position recognition unit 23 and the weather recognized by the weather recognition unit 25, the vehicle use situation recognition unit 24 moves the processing to step S75, sets a bad weather traveling flag to “1”, and moves the processing to step 361. On the other hand, when it is not recognized that the vehicle 10 travels in bad weather, the vehicle use situation recognition unit 24 moves the processing from step S60 to step S61.

In step S61, the vehicle cabin interior information acquisition unit 21 moves the processing to step S62 when the vehicle position recognition unit 23 recognizes that the vehicle 10 arrives at the parking lot St (see FIG. 1 ) as a return spot and stands still and the power source state recognition unit 26 recognizes the power source OFF state. On the other hand, when the vehicle 10 does not arrive at the parking lot St or is not in the power source OFF state, the vehicle cabin interior information acquisition unit 21 moves the processing to step S50 in FIG. 4 and repeatedly executes processes of step 350 and subsequent steps.

In step S62, the vehicle cabin interior information acquisition unit 21 photographs the vehicle cabin interior by the vehicle cabin camera 43 and acquires an image of the vehicle cabin interior. In next step S63, the dirt factor element recognition unit 22 moves the processing to step S76 when the concordance rate between the image of the vehicle cabin interior and the reference image is the first predetermined value or smaller, sets a vehicle cabin change flag to “1”, and moves the processing to step S64 in FIG. 6 . On the other hand, when the concordance rate between the image of the vehicle cabin interior and the reference image is higher than the first predetermined value, the processing is moved from step S63 to step S64 in FIG. 6 .

In step S64 in FIG. 6 , the vehicle cleaning handling unit 27 moves the processing to step 380 when at least one of the child-in-vehicle flag, the vehicle cabin eating-and-drinking flag, the target destination flag, the bad weather traveling flag, and the vehicle cabin change flag is set to “1”.

Referring to FIG. 3 , a first renting fee discounting unit 102 of the vehicle renting system 100 moves the processing to step S20 when the vehicle cabin interior non-dirty information transmitted from the vehicle control device 20 is received in step S4 and executes a first renting fee discounting process. The first renting fee discounting process is a process of discounting a renting fee of the vehicle 10 at a first predetermined amount or a first predetermined rate from a regular fee. As described above, the renting fee of the vehicle 10 is discounted, and an incentive to carefully use the vehicle 10 without making the vehicle cabin interior of the vehicle 10 dirty may thereby be given to the user U.

Further, a second renting fee discounting unit 103 moves the processing to step S30 when the vehicle cabin interior cleaned information transmitted from the vehicle control device 20 is received in step S5 and executes a second renting fee discounting process. The second renting fee discounting process is a process of discounting the renting fee of the vehicle 10 at only a second predetermined amount or a second predetermined rate from the regular fee. As described above, the renting fee of the vehicle 10 is discounted, and an incentive to clean the vehicle cabin interior in returning the vehicle 10 may thereby be given to the user U. Note that the first predetermined amount and the second predetermined amount may be set to the same amount or may be set to different amounts. Also, the first predetermined rate and the second predetermined rate may be set to the same rate or may be set to different rates. For example, the first predetermined amount is set larger than the second predetermined amount, or the first predetermined rate is set higher than the second predetermined rate, and the incentive to use the vehicle 10 without making the vehicle cabin interior of the vehicle 10 dirty may thereby be enhanced.

Further, the vehicle renting management unit 101 moves the processing to step S40 when the second vehicle cleaning information CLi2 transmitted from the vehicle control device 20 is received in step S6 and sets a renting prohibited period of the vehicle 10. The renting prohibited period is set in consideration of a period needed for cleaning of the vehicle cabin interior of the vehicle 10. In next step S41, the vehicle renting management unit 101 prohibits renting of the vehicle 10 until the renting prohibited period elapses. This enables avoidance of a case where a user feels discomfort due to renting of the vehicle 10 in a state where the vehicle cabin interior is dirty.

4. Other Embodiments

In the above embodiment, the vehicle management system 1 is composed of the vehicle control device 20 and the vehicle renting system 100; however, configurations included in the vehicle renting system 100 are incorporated in the vehicle control device 20, and the vehicle management system 1 may thereby be composed of only the vehicle control device 20. Further, the vehicle management system 1 may be composed of only the vehicle renting system 100 in which configurations included in the vehicle control device 20 are incorporated.

In a case where the vehicle cabin interior information acquisition unit 21 is included in the vehicle renting system 100, the vehicle cabin interior information acquisition unit 21 acquires pieces of information such as the image of the vehicle cabin interior photographed by the vehicle cabin camera 43, the odor level in the vehicle cabin detected by the odor sensor 45, and the sound in the vehicle cabin detected by the microphone 44 by receiving those from the vehicle 10. Similarly, the vehicle position recognition unit. 23 receives information of the present position of the vehicle 10, the present position being detected by the automotive navigation system 50, from the vehicle 10 and thereby recognizes the present position of the vehicle 10.

In the above embodiment, the vehicle renting management unit 101 included in the vehicle renting system 100 sets a non-use period of the vehicle 10, and the first renting fee discounting unit 102 and the second renting fee discounting unit 103 perform the first renting fee discounting process and the second renting fee discounting process for discounting the renting fee of the vehicle 10.

In the above embodiment, the vehicle cleaning handling unit 27 transmits the first vehicle cleaning information CLI to the user terminal 90 and transmits the second vehicle cleaning information CLi2 to the maintenance management server 200. As another embodiment, only either one of the first vehicle cleaning information CLi1 and the second vehicle cleaning information CLi2 may be transmitted.

In the above embodiment, when the vehicle 10 arrives at the return spot and the power source is turned off in step S61 in FIG. 5 , the vehicle cleaning handling unit 27 transmits first vehicle cleaning information to the user terminal in step S80 in FIG. 6 and transmits second vehicle cleaning information to the maintenance management server 200 in step S90. In this case, the user U checks the first vehicle cleaning information advising cleaning of the vehicle cabin interior after arriving at the return spot, but it is possible that handling of cleaning may not be performed at the return spot.

Accordingly, as another embodiment, the first vehicle cleaning information and the second vehicle cleaning information may be transmitted at a timing when the user U sets the destination of movement by the vehicle 10 to the parking lot St as the return spot of the vehicle 10 by the automotive navigation system 50 after the vehicle use situation recognition unit 24 recognizes that the user U visits the predetermined area or the predetermined facility by the vehicle 10 or that the vehicle 10 is used in bad weather. In this case, the user U who has checked the first vehicle cleaning information may stop by a cleaning facility such as a car wash and clean the vehicle cabin interior of the vehicle 10 before arriving at the return spot. Further, the maintenance management server 200 may prepare for cleaning of the vehicle cabin interior of the vehicle 10 before the vehicle 10 arrives at the return spot. Further, when it is recognized that the vehicle 10 stops by the cleaning facility based on the position of the vehicle 10 recognized by the vehicle position recognition unit 23, the vehicle cabin interior cleaning estimation unit 28 may estimate that the vehicle cabin interior of the vehicle 10 is cleaned.

In the above embodiment, the portable user terminal 90 is described; however, a user terminal of the present invention may be in-vehicle equipment that is installed in the vehicle 10, is used by the user U, and has a function of performing communication with the outside via the communication network 500.
